I don't remember this being a feature of XP's Windows Explorer.
But I now have Windows Vista, and there is certainly a section above the Status bar at the foot of Windows Explorer which gives more details than in XP's version.
With your Explorer open, go to the View menu option, (the 3rd one in the row of File - Edit - View - Tools - Help), and look at what options you have for toolbars. Then in the same menu option select "Choose details". That will allow you to choose specific columns in the right hand pane.
On previous Windows XP installation I had a resource I considered very useful chiefly as I needed to know the date & hour I took a picture with digital camera(it showed me not the date the file was altered but the date & hour picture was actually taken). It used to appear the time info as well as the model of the camera at the FOOT of every Windows Explorer?s window (I don?t mean Internet explorer). Recently I had to format and reinstall then I noted that no longer have this resource available. As far as I can remember neither I have installed nor configured anything to do this.
Does anyone know what?s supposed to be done to have this feature back again?
